Taxes and assessed value for 823 40 Street
The city's Department of Finance assessed this lot at $427K for the 2026 tax year. That works out to $107K per residential unit. Assessed value is what the city taxes, not what the building would sell for, and the two routinely differ by a wide margin.

Rent stabilization at 823 40 Street
